1、父類 @Embeddable @Inheritance(strategy = JOINED) public abstract class BaseEntity implements Serializable { private static final long serialVersionUID = 1L; @Column @Temporal(TemporalType.TIMESTAMP) private Date createDate; @Column @Temporal(TemporalType.TIMESTAMP) private Date updateDate; ... //省去get\set } 2、子類 @Entity @Table(name = "user") public class UserEntity extends BaseEntity implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private long id; private String user; private String password; private String role; private String tel; private String mail; ... } 3、Repository接口 @Repository public interface UserRepository extends CrudRepository<UserEntity , Long> { public UserEntity save(UserEntity user); } `` 4、controller中調用save方法的時候， user.setCreateDate(new Date()); 這個方法最終并沒有被save進去，不知打為何 下面是springboot打印的日子 Hibernate: insert into user (mail, password, role, tel, user) values (?, ?, ?, ?, ?)com.example.demo.entity.UserEntity@78730d83 可以看到里面并沒有createDate
